# Problem: Four Fe2+ ions are key components of hemoglobin, the protein that transports oxygen in the blood. Assuming that these ions are 53Fe2+, how many protons and neutrons are present in each nucleus, and how many electrons are present in each ion?

###### FREE Expert Solution

We are being asked to determine the number of protons and neutrons present in each nucleus and the number of electrons present in each ion

An element can be represented as:

You can determine the identity of the element using its atomic number:

Atomic number (Z):

represents the identity of the element
reveals the number of protons
in a neutral element:

# of protons = # of electrons

Mass number (A)

reveals the number of protons and neutrons

mass number = # of protons + # of neutrons

We will do the following steps

Step 1: Determine the number of protons

Step 2: Determine the number of neutrons

Step 3: Determine the number of electrons

Given: 53Fe2+
